Low voltage, DC power supply, battery, solar power supply, in remote mountainous areas and field lighting, such as lack of electricity, less electric field. Contrast: LED lamp will have stroboscopic phenomenon under AC drive as common incandescent lamp, while ordinary energy-saving lamp has no stroboscopic phenomenon. Strobe will make eyes fatigued easily. Every LED light bulb is too bright, Snowing Musical LED Lantern Prelit Christmas Decoration it will strongly stimulate the eyes,Snowing Musical LED Lantern Prelit Christmas Decoration not to look directly, even for a short time, but the ordinary energy-saving lamp is relatively gentle! The angle of illumination is limited. Generally, it can only illuminate 120 degrees, while the ordinary energy-saving lamp can illuminate almost 360 degrees.
The brightness of the illuminated room is not better than that of the energy-saving lamp, because the LED only has high brightness in the narrow angle of direct vision,Snowing Musical LED Lantern Prelit Christmas Decoration and the light quickly decreases when it deviates from that angle. Therefore, the advantages of LED energy-saving lamp as indoor lighting lamps are not necessarily more obvious than ordinary energy-saving lamp, but as a torch, desk lamp, spotlight and other lamps only need to illuminate the narrow angle of the lamp is still very excellent.
Buy: LED brightness (MCD) is different, the price is different. The LED used for LED lamps should conform to Class I standard of laser grade. LED with strong antistatic ability, long life and high price. Usually, LED with antistatic capacity greater than 700V can be used in LED lighting. LED with the same wavelength and the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products. Leakage current LED is a single-conductor emitter. If there is reverse current, it is called leakage current. The LED with large leakage current has short life and low price.
LED with different luminous angle uses has different luminous angle. Special light-emitting angle, the price is higher. If full diffuse angle, the price is higher. The key to different quality of life is life,Snowing Musical LED Lantern Prelit Christmas Decoration which is determined by light decay. Low light decay, long life, long life, high price. Wafer LED emitters are wafers, different wafers, prices vary greatly.
